circular inclusion warning with lupdate tool

[Christophe Dumez]

Since updating from Karmic (Qt 4.5) to Lucid (Qt 4.6), I get a lot of warnings when using lupdate tool:

/usr/include/sys/cdefs.h:25: circular inclusion of /usr/include/features.h
/usr/include/limits.h:125: circular inclusion of /usr/include/limits.h
/usr/include/wchar.h:37: circular inclusion of /usr/include/stdio.h
/usr/include/sys/ucontext.h:23: circular inclusion of /usr/include/signal.h
/usr/include/glib-2.0/glib/gtestutils.h:28: circular inclusion of /usr/include/glib-2.0/glib.h
/usr/include/glib-2.0/glib/gurifuncs.h:30: circular inclusion of /usr/include/glib-2.0/glib.h

/usr/include/gtk-2.0/gtk/gtksignal.h:32: circular inclusion of /usr/include/gtk-2.0/gtk/gtk.h

lupdate seems to work though but it takes more time than usual.
